This app presents you the textcontent of the standard Android-clipboard, which is the memory you work with when you use "copy", "cut" or "paste" when typing on your keyboard anywhere in Android.

You can see what is current in die textbuffer of the clipboard, and editing this directly changes the chlipboards content systemwide. And you can share the clipboards content, so this clipboard-app is the right supplement for apps which have a copy- but not a share-functionality.
